SA3S5W-03

Attenuators Overview

The SA3S5W-03 is a fixed attenuator manufactured by Fairview Microwave, designed for RF signal management. It provides a nominal attenuation of 3 dB with a maximum operating frequency of 3 GHz and a minimum frequency of 0 Hz. The component features SMA connectors in a female-to-female configuration and operates at a standard impedance of 50 Ohms. It is rated to handle up to 5 Watts of power and maintains a Voltage Standing Wave Ratio (VSWR) of 1.45. The unit utilizes a heatsink body construction and weighs approximately 77.791 grams.

Attenuators Feature Summary

• Incorporates a heatsink body design to facilitate thermal dissipation during operation.
• Features SMA female-to-female connector interfaces for standardized integration.
• Provides fixed 3 dB attenuation within a 0 Hz to 3 GHz frequency range.

Attenuators Applications

• Precision measurements
• Instrumentation systems
• Prototyping and characterization

Attenuators Procurement Notes

Verify the specific connector gender configuration and power rating against project requirements before ordering. Confirm that the 5-watt power handling capacity meets the system's peak signal levels. Ensure the SMA interface type matches existing cabling infrastructure. Check current availability status as supply may be restricted or subject to production lead times depending on the distributor channel.

Attenuators Selection Notes

Select this model when a low-loss, fixed 3 dB reduction is required below 3 GHz. The 5-watt rating suits moderate power applications where higher-capacity units are unnecessary. The heatsink body supports continuous operation without excessive temperature rise. Consider the physical weight and dimensions for space-constrained enclosures. Verify compatibility with 50-Ohm system impedance standards.
